IMPROVEMENT IN WINDOW-BLINDS.

Specification forming part of Letters Patent No. 182,075, datedSeptember 12, 1876; application filed July 35, 1876.

To all whom it may concern:

Be it known that I, Amos A. JAQUA, of the city, county, and State of New York, have invented a new and useful Improvement in Window-Blinds, which improvement is fully set forth in the annexed specification, reference being had to the accompanying drawings.

The nature of my invention is the construction of window-blinds so that the slats of the blinds shall revolve upon their tenons without involved in the use of the old style of blinds.

By the use of myvinvention another great difficulty attending the use of the old style of blind is obviatedviz., the sticking of the slats in one position when painted newly, or from other causes.

My improvement also makes the blinds far more durable. It is also far more convenient than the old arrangement of slats and blinds, for the slats can be placed at any angle desired, and will always remain so, until, by design, their angle is changed.

Ingthe drawings, Figure 1 represents a front view of a window-blind containing my improvement. Fig. 2 is a vertical section thereof in the line a; m, Fig. 1, looking in the direction of the arrow marked opposite to that line. Fig. 3 is a cross-section of the same in the line 3 y, Fig. 1. Fig. 4 shows my improved tenon for window-blinds, blind-doors, shutters, and other articles of like nature. Fig. 5 is an end view of one of the blind-slats 0, representing the slit in the slat.

My improvement'consists of a blind havingaplate or plates, I, of metal or other suitable material, secur'edto the inside edge of the stile or stiles A. These stiles A are grooved,

' so as toreceive the plate or platesI and at-- tachments. The said plates I are perforatedwith holes, at suitable distances apart, to re-- ceive the tenons a of the slats B. These tenons a. are made of metal or other suitable material, and are provided with flanges O.

' Upon the back of one of these plates I, after the tenon a has been inserted through said plate I, and upon the end of said tenon a, are small metal clips E, perforated with holes, to pass over the tenon a, and bent so as to hold the rack G in position. Said rack G is 0on structed with teeth", which take into the pinions D, which are also perforated with holes. in their centers to pass over the endsof the tenons a, and are thus secured to the tenons a. The plate I, upon the other stile A of the blind, is merelyperforated with holes, at proper distances to receive the tenons a, and form a proper bearing for said tenons a. The slats B of the .blind are made square upon both ends. At each end of the slats B is out a slit, 0, in which is inserted the tenon a, provided with oneor more flanges, 0, upon either side of the slats B. The flange or flanges G hold the slat B in position, making it firm and secure.

To the rack F, which operates the pinions. D, is secured a lug the handle H. 1

I do not confine myself to this mode of operating the rack F; but the same may be worked by any suitable device.

Themotion transmitted from the rack F to pinions D is communicated to the rack G, and. thence to the tenons a of the blind-slats Br.

The pinions D, when secured to the tenons a, as shown, by being passed over the ends of said tenons a, hold in position the rack G, tenons a, and plates I, and clips -E, making the running parts of the blind secure and firm,

1. The clips E', in combination with the rack G, pinion D, and operating-rack F.

2. A blind-slat, B, with one or both ends square, and perforated, so as to receive the tenon a.

3. The blind-slat B, in combination with the blind-slat tenon a.

4.. The combination of the racks G and F, pinion D, clips E, plates 1, tenon a, and slats B, for the uses. and purposes mentioned.

In testimony whereof I have hereunto set my hand this 18th day of July, 1876.

AMOS A. JAQUA. In presence of- CHARLES G. 00E, Louis W. FBosT.
